Tomoko Sakurai

Tomoko Sakurai (さくらい ともこ) is the technical sister of Tomoki Sakurai. She debuted in chapter 43 of the manga, and became a completely separate character. She has her own individual personality. In said chapter, she merely wanted to keep her newly obtained life, make the other girls at school her friends, and be accepted.

Appearance
Tomoko has dark black hair accompanied by two clips attached to the upper part of the strand of hair going down her face, one red and the other being blue. She has dark brown eyes as well.

Tomoko resembles her technical mother Tomoyo Sakurai very much. Her measurements are: weight 43 Kg, height 157 cm (5'2),  hips 87 cm,  bust 75 cm, Waist 49 cm.

Abilities
Tomoko, when separated from Tomoki, does not have any remarkable abilities. However, it was shown that she gained the ability to merge with Tomoki at will upon becoming an individual. However, unless Tomoko is manipulated, she does not have even the slightest interest in merging with him. If she is manipulated, then she unwillingly, and unfortunately, goes on a perverted rampage that she wouldn't do under normal circumstances, as she is actually timid and shy. She herself is not actually perverted. It is simply a side effect of her having been trapped inside of Tomoki.

Personality
Tomoko, as an individual character when separated, is shy, timid, and scared of interacting with people. This is a sharp contrast to the ditsy, clumsy, social butterfly personality Tomoki pretends to have when he disguises himself as her. But as stated, Tomoko herself is the polar opposite. She is sexually attracted to males, and possibly females as well. Her attraction to females is up for debate, as she only went on a perverted rampage because she had her mind manipulated beforehand. Tomoko is very feminine, but that's only logical for her, as she is an actual girl when separated. Tomoko is also extremely emotional, and can be prone to crying if she is thought of as a boy by the others. An example of this is shown within her debut chapter, where she broke into tears after being lied to by Tomoki that she was really a man.

While she prefers to be alone, she still desires friendship with other girls, and to be accepted.

Separated From Tomoki
Her true personality was shown when she became an individual in chapter 43. When Tomoko was separated from Tomoki in that chapter of the manga, it was apparent that she was very confused and did not know where to go as she was just given freedom as a person. We could see her picking petals off of a flower after she had begun to develop feelings of love towards Sugata. Again, showing that she is in fact an individual separate from Tomoki. When Tomoki found her and told her to "merge" back with him, she seemed hesitant but agreed at first. However, upon seeing Sugata, she began to realize that she was truly in love, and enjoying her own life.



Tomoki, desperate, decided to try to, "reawaken", her masculinity, which the scared girl obviously did not have. When Tomoki began to tell her lies such as that she was really a man, was really not a girl, and needed to "merge" back with him, it only caused her more distress and confusion. Finally, after Tomoki's last resort of showing her a porno magazine in hopes that it would convince her to join with him, Tomoko was pushed over the edge and, with tears in her eyes, called him a cockroach after directly telling the boy that she never wanted to see him again.

Shortly after this had all taken place, we see Tomoko yet again, who has actually begun to make friends with the students at her new school. However, Ikaros, enraged because her master Tomoki was unable to pet her head, attempted to force Tomoko into merging with Tomoki. This frightens Tomoko and, desperate, tells Ikaros that in a way, she is her Master as well. Of course, she only said this to stop Ikaros from harming her. Hearing this, Ikaros believes the lie, and pauses, as she does not want to hurt her "Master." However, she trips, falling on top of Tomoko and shoving the latter's face directly into her breasts. Immediately, Tomoko begins to feel something very intense and unusual. This feeling was the perversion which was unfortunately left inside of her as a side effect from being trapped inside of Tomoki for so long. Ikaros then realizes that she may have found a way to convince Tomoko to merge with Tomoki. Ikaros then fires Artemis to cut off the clothes of Tomoko's new friends. This apparently aroused her yet again. Shortly after these intense sensations began to grow stronger, Astraea was thrown at her. In Tomoko's confusion and feeling as if something was missing, Ikaros presented Tomoki to her. Tomoko, after having her mind manipulated by not only Tomoki, but Ikaros as well, decides to merge with Tomoki. However, as stated, her decision to merge was only due to her being manipulated, and not a conscious choice. Tomoki's lies to her, Ikaros taking advantage of the perversion that she could not help having, and the fact that she was helplessly confused during all of this, lead the girl to a state of mind in which she agreed to merge with Tomoki. However, before this happens, Tomoki stops her and claims that if they work together, they can touch twice the amount of breasts. Tomoko, with her mind having been warped, agrees. The two of them then began chasing Tomoko's new friends. Sohara then attempts to stop Tomoki from touching the other girls, and manipulating Tomoko's mind any further, by giving him one of her karate chops. However, this creates a tiny clone of Tomoko and shrinks Tomoki even further. Sohara relentlessly attempts to karate chop him, but it only makes matters worse. After this, Tomoko merged with Tomoki until at least the ending of the manga.

Due to the events that took place surrounding her in the manga, it is rather likely that Tomoko was separated from Tomoki forever a short time after the series ended. This can be assumed by taking into consideration that she isn't just a transformation anymore. She is now an actual person, with her own thoughts and emotions.

Before Separated From Tomoki
Before she became a separate character altogether, "Tomoko" was merely a transformation that Tomoki would use to spy on girls. Of course, when she was separated into an actual person/girl, this fact ruined her reputation among many people, leading to complications with her relationships with the rest of the main girls. However, Tomoko as an individual character, as previously stated, is kindhearted, loving and innocent. This is the polar opposite to the pervert Tomoki would hide when he transformed into her.
